Description
Technical field
The present invention relates to pilot tone bearing technology, more particularly to a kind of demodulation pilot tone to determine method and device.
Background technology
In Long Term Evolution (LTE, Long Term Evolution) Release8/9, in order to be carried out to the quality of channel
Measure and the data symbol of reception is demodulated, devise public reference signal (CRS, Common Reference
Signal).User equipment (UE, User Equipment) can carry out channel measurement by CRS, so as to determine that UE carries out cell
Gravity treatment and it is switched to Target cell.Also, the measurement of channel quality is carried out under UE connection status, when interference rank is higher
When, physical layer can be disconnected by high-rise relevant Radio Link connection failure signaling.In LTE Release 10, it is
Further improve the average availability of frequency spectrum of cell and the throughput of the cell edge availability of frequency spectrum and each UE, it is fixed respectively
Two kinds of reference signals of justice：Channel information reference signal (CSI-RS, Channel State Information Reference
Signal) and demodulated reference signal (DMRS, Demodulation reference signal), wherein, CSI-RS is used for channel
Measurement, by the measurement to CSI-RS can calculate UE need to eNB feed back pre-coding matrix index (PMI,
Precoding Matrix Indicator), channel quality information indicate (CQI, Channel Quality Indicator) with
And order instruction (RI, Rank Indicator).UE can be made pellucidly to receive downlink data using DMRS, without knowing base station
The precoding weights that side uses, in this way, reducing Physical Downlink Control Channel (PDCCH, Physical Downlink
Control Channel) load while, also reduce limitation of the code book to weights.In addition, it can also be supported using DMRS alone
Family multiple-input and multiple-output (SU-MIMO, Single User Multiple Input Multiple Output) and multi-user are more
Into Mobile state between input multi output (MU-MIMO, Multiple User Multiple Input Multiple Output)
Transparent switching, carry out Interference Estimation using DMRS, the interference elimination performance of receiving side can be greatly enhanced.
The transmission of pattern TM1~TM6 is transmitted using CRS in R8, is also utilized for the pattern of this open loops of TM3
CRS is demodulated, and has only carried out to TM1, TM2, TM4~TM6 the optimization based on DMRS transmission in R9~R10 stages, not
Have and this open loop modes of TM3 are carried out based on DMRS to optimize.In future version consider it is energy saving, resource save etc. it is many because
Element, CRS needs gradually to fade out, so needing to be designed based on DMRS for this open loop sending modes of TM3.At present, not yet
There is the related art scheme for carrying out TM3 open loop sending modes based on DMRS can be for reference.
The content of the invention
In view of this, can be reasonably it is a primary object of the present invention to provide a kind of demodulation pilot tone to determine method and device
The distribution that pilot tone meets is distributed in subframe, the interference between different DMRS groups is reduced, is conducive to user equipment and efficiently and rapidly solves
Adjust channel.
